Michigan Technological University is putting out plans for what
appears to be a MIG printer. g Check it out. Looks IFFY to me,
but I hope it grows. It's entirely Open Sourced.

I tried freehand TIG "printing" once, actually additive sculpture.
Other than being limited to details of at least the puddle size it
went pretty well.
